We’re all adults, right? Good. Flatulence is the medical term for passing of gas through the rectum. It’s the appropriate word when conversation necessarily turns to this most human of activities.
But for those of a more sensitive or obscure disposition, here are other synonyms and phrases for, uh, farting: air biscuit, bottom burp, bafoon, cut the cheese, barking tree spider, foist, break wind, fizzle, prat whids (16th century British slang meaning “the buttocks speak”), tail scutter, rouser, shoot the bunny and trump.
No really, that last word dates back to the 15th century and is related to the sound of a trumpet.
